ing nuts 31 for the reception of the shaft 28 and4 also having an openin with a key whereby it is splined to the shaft 12. j A second nut structure 31a is threaded onY the shaft 14 and With the bracket 27 provides bearings for a spindle 23. On this latter are loosely mounted t'wo sets of arms 21 and these in turn provide bearings for four spindles respectively carrying three brushes 17, 18 and 19, together with a bufling roll 20. Each of said four spindles has fixed to it a gear Wheel 22 and all of th/ese gear wheels mesh with another gear/Wheel 52 fixed on the central spindle 23, 'which also has' fixed to itfa sprocket. This sprocket is connected by a chain 24 with a sprocket on the boss 25 of a beveled gear wheel 26 carried by the bracket 27 in such manner as to mesh with the second beveled gear 29 splined'to the shaft l2.

For the purpose of compelling the brush carriage to turn in but one direction I provide a ratchet wheel 65 on a boss or hub 116 fixed to t-he arm struc ture 21 and mount on the nut structure 31a of the shaft 14 a spring paWl 66 'in such a position as to engage said ratchet wheel. The brushes 18, 17 and 19 are respectively a hard brush for cleaning dust from the shoes, a blacking brush and a polishing brush, While the bufling roll 20 is made of any suitable material. In order to provide the brush 17-with blacking, I provide an annular reservoir 32 for blacking, fitting it around the eentral spindle 23 of the brush carriage 13 and connecting to it a duct 33 extending parallel with said spindle 23. This duct is perforated on the side immediately adjacent the I 'brush 17 to which itis designed'to supply blacking, so that a proper supply-of .the lat- Y ter isprovided for said brush. The c arriage 13 with its shafts 14, 12 and 28 and .their various fittings, being supported on the small wheels 34, is normally drawn toward the shoe to be operated on, by weights 36 which are connected to it through cords 37 .v These cords pass around pulleys 38 so that they act in the desired direct-ions,

, and as above indicated, the shaft 10 is bracket 27 is provided with two projections 54, through both ot which passes a gear changing rod 40 extending longitudinally ot the. casing l and slidably monntedin suitable bearings in the main-Shaft-supporting rod 40 has an arm 45 engaging this sleeve so as to be capable of: movlng it in order to bring intomesh the gears 47 and 49. or the gears 48 and 50. `This rod 40, adjacent the arm 45, has an abutment with a sprin 41 and a disk 39, so placed'as to be engage by one of-'the projections 54 of the brush carriage' .when this approaches one end of its path of movement. Similarly on the other end' of the rod 40 is mounted an abutment having a spring 56 and av second disk 349 placed to be engaged b the second of the projections 54 of the addition there are fixed to the bracket structure 27 of the brush carriagetwo arms 42 and 57, the first of'which is so placed as to be capable of engaging a lever 43' to operate a catch 44 normally engaging a notch 1n the rod'40.' The arrangement of parts is such that after the projection 54 has compressed the spring 41 to a predetermined extent said arm 42 engages the lever 43 and raises the catch 44 out of the notch in said rod, thereby permitting it to move longitudinally under the act-ion of said spring, a sufficient d-istance to shift the clutch sleeve 46. The opposite end of the rod 40 is also provided with arnotch capable of being engaged by a latch 55 so placed as to be actuated by the,

rush carriage. In

rod 57 when the brush carriage has moved to a point adjacent thesecond end of its pat-h of movement. The arrangement of parts is suchthat after the second projection 54 has compressed the spring 56 to a predetermined extent, the arm 57 disengages the latch 55 from the shaft 40, allowing it to move under the action of the spring 56 a sufficient' distance to move the clutch sleeve Y v 46 in a 'direction opposite that heretofore! noted, for a distance sufficient to bring the gears 49 and 47 .into engagement. Y l

The rotatable brush carrying arms of the carriage 13 are provided with a series of four pins 61 and there is mounted 'on the carriage-and-shaft-supporting structure a pair. of forked abutments 62 and 62a soA placed that as the brush carriage approaches o'ne end ot' its path of movement, one ot' the,v

pins 61 strikes the forked abutment 62, with the'result that the arms 21 andwith them the brushes which they carry are turned through an angle ot' substantially 90 degrecs. Similarly at the opposite end of its ath of movement another pin 61 engages the forked abutment 62n so -that the brushes are again turned in the same direction as before through an arc of 90 degrees. Each of the abutments 62`and 62 is pivotally mounted and yieldingly held Ain"a definite positiqn by a spring so thatl its forked end is free to follow the curved path taken by the in 6l as it is moved.`

While the ratchet wheel 65 and its pawl 66 insures that the brush carriage shall turn in but a single direction, itis advisable to provide means whereby itJ shall be prevented from turning inore than @O degrees under the action ot' the abutinents 62 and G2 and Shall be held when so turned. For this purpose there are on the brash rai-ringe tour projecting lags (3, and a. pivoted trip bolt" G3 designed to cooperate therewith7 and pivotally nio'nnted on a portion of' the nut. Structure 31a. This trip bolt (S23 is normally held from turning; on its pivot by a lever (Btl engcfaging` one ot' its ends and also sin ported in a Suitable manner on the nut strneture 3in1 On this lever 69 :ie a. roller (37 so placed as to be Capable of engaging one ot' two abntrnents 68, when thev carriage approaches either end of its path oit' movement. By such engagenient the lever 69 is swung on its pivot out of engaeinent'with the trip holt (13, which is thus jt'ree to tnrn on its snpportino' pivot and permit the passage ot one ot' the i)rojeeting lugs (3ft with consequent rotation ot the hrnah supportingI structure Y of the carriage 13.

"`The above described parte are designed to operate on the` sides and heels of a shoe, and for polishing the front and top of the shoe lt provide a Substantially rectangular' t'ranie 70 loosely mounted on a support-ing shaft Slt, operative" in hearings in the ende ot a 'pair of arn'is 7l.

for the purpose of drawing or holding down the arms with their frame. Fixed to the shaft 73, isa curved .segment 97 having connected to it one of the cords 113, Which passes around a pulley 99 mounted on the structure which supports the shafts 12, 28

and 13 and at its opposite end, connected to a carriage 100, movable longitudinally of Athe casing 1. A rail v101 is mounted on said shaft carrying structure so as tov extend parallel to the shaft 14 and on the side of this rail is mounted a ratchet 103 in such a position that its teeth may be engaged by apaWl 102 on thevcrarriage 100,. when this latter is in 'such a position that through the cord 113 it holds the band supporting frame u 70 in its loWermost position. This carriage 100 has pivoted to it a lever 109 and also a projecting member 106 forming a cam.

The nut structure 31eL heretofore referred to has pivoted to it a lever 105 capable of engaging a notch or recess'ofsaid cam 106 from which it maybe disengaged by the action of a projection 112 forming' an abut- -ment which is supported in 'any suitable 'mannen The lever 109 is capable of engaging the pawl 102 so to reta-in it 1n engagement With the ratchet 103 and Vfor the purpose of actuating this lever, I provide a trip bolt 10S on the nut .structure 31a'.

lVith the above described arrangement of parts, the main shaft 10 may be driven from any` desired. source of power and if the user of the machine places his foot upon the structure 8. and moves it with the same into the position shownin dotted lines in Fig'. 1, the sides of the shoe` Will first be cleaned by the brush l18. In order that .this operation shall be carried out, the carriage 13 on'each side of the Vshoe is moved longitudiv nally of the casing by reason`oftle fact that power is transmitted from the .shaft 10 through the gear Wheels l.117, through the `shaft 12,` thenceathroughithe gear'wheels 51', 50 and 48 to the. shaft 28 and through the' sprocket VWheels- 15', chain v16 and sprocket wheel 115V to theshaft '14. Since this latter as' wellas'the shaft 28 is threadthe casing, one of its pins 61 strikes a forked structure 62a and during the last part of its forward moiement the arms 21 with their brushes are turned about the spindle 23 as an axis through an angle of 90 degrees; the paWl 66 yielding to permit such turning. A

- Just before the pin 61 engages the forked struct-ure 62l the abutment 68 strikes the this latter so as to release the trip bolt 63 and permitting one of the lugs 64 on one of the arms 21 of the carriage to pass. By the time that the brushes and their supporting structures have made their 90 degree turn, the lever 69 has again engaged the trip bolt 63, so thatiit engages the next lug 64 and roller 67 of the lever 69, thereby turning'.

prevents further turning of the brushes.

lAs the .brush carriage approaches the forward end of its path of movement, the projection 54 first. engages vthe disk 39 and after compressing't-he spring 56 brings the arm 57 into engagement- With the latch 55, thus freeing this latter from the notch in the rod 40. Said rod thereupon moves longitudinally under action of the spring 56 and through the arm 45, shifts the gear 4S out of engagement with the gear 50 and brings the gear 47 into engagement with the gear 49. As a consequence, the direction of rotation of the shafts 28 and 24 is reversed and both brush carriages are started toward the rear end of the machine, each With its second brush 17 in position to engage'the sides of the shore.

When the carriage has-moved to Within a predetermined dittance of the rear end of the easing, its leijer 69 is again engaged by y one of the abutments V68, thus freeing the carriage from the restraint ofthe trip bolt 63 and permitting the brushcarrying structure to be turned through another 90 'degrees, by reason of engagement of a second one 0f the pins 61 With the forked abutment 62. Since the brush 17, as before noted, re-

ceives blacking from. the reservoir 32 and. tube 33, such blacking is .applied by it to" the' sides of the shoe,so that `when the brush carriage is again started forward,`its third brush 19 acts to remove the surplus blackversal of movementof the carriage is.
